WEFT-REPLENISHING LOOM.

Specification of Letters Patent.

Patented Apr. 2, i912.

Application filed December 5, 1910. Serial No. 595,599.

To all whom it may concern.'

Be it known that I, EPPA H. RYoN, a,

citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Weft- Replenishing Looms, 4of which the following .is a specification.

y which receives a bobbin from the compartshuttle.

ment from which a bobbin is released, and carries it into the path of a transferrer above the stationary Vshuttle box on the lay, preparatory to being transferred into the active My bobbin conveyer preferably has a pivoted arm, movable back and forth in the arc of a circle in unison with the movement ofthe shifting shuttle boxes, in this instance six in number. Said arm carries a stud, movable up and down thereon, from which a connecting rod extends to the filling carrier or bobbin conveyer; when said stud occupies a position at the outer end of the arm,

the conveyer will be move'd to the lower end of that compartment which corresponds to the shifting yshuttle box at the level of the race-way of the lay.

W'hen a change of filling is indicated by the substantial or practical' exhaustion of filling in the active shuttle, a bobbinl which has the same color or character of filling as the bobbin in the shuttle, will be dropped from a compartment in the stationary magazine into the conveyer', and at the same time, on the further movement of the releasing mechanism for the bobbins, the stud above mentioned will be moved to the inward end of the arm, thus coinciding with the axis or' fulcrum of the arm, and move the conveyer, with the dropped bobbin, to the transfer position under the transferrer. On the backward movement of the lay the stud is returned to its first position at the outer end of the arm, and the conveyer registersV with the respective compartment of the magazine, according to the position of the shifting shuttle boxes.

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

I have shown in the drawings a detached portion of a lstationary magazine of the type above referred to, with my conveying mechanism combined therewith, sufficient to enable those skilled in the art to .understand the construction and operation thereof.

Referring to the drawings z-Figure 1 is an inner end view of the stationary magazine, with my conveying mechanism combined therewith. Fig. 2 is a section, on line 2, 2, Fig. 1, looking in" the direction of arrow a, same ligure. Fig` '3 corresponds to Fig. 1, but shows some of the parts shown in Fig. 1, in a different position. Fig. 4 is a section, on line 4, 4, Fig. 3, looking inthe direction of arrow b, same figure. Fig. 5 shows, on an enlarged scale, the lower part of the conveyer shown in Fig. 3. Fig. 6 is a side view of the conveyer shown in Fig. 5, looking inthe direction of arrow c, same figure, and, Fig. 7 is a plan view of the conveyer, looking in the direction of arrow d,

' Fig. 6.

In the accompanying drawings, 1 is .the breast beam of the loom, `2 is the lay, carried on the lay sword 3, which is pivotally mounted at its lower end, not shown.

4 is a single stationary shuttle box at the magazine end ofthe loom, and 5 is a shuttle in said`l box.

6 is a stand secured to the breast beam 1, which has rigidly connected thereto the inner end` 7 of the stationary magazine, which in this instance has six vertically extending compartments or guide-ways 7 for the heads 8 of the bobbins 8. The bobbins 8 are ar'- ranged in six sets or series, one set in each compartment. Each compartment or guideway is provided at its lower endv with mechansm for supporting the sets of bobbins therein, also for releasing the lowestbobbin in each set, preparatory to being conveyed to the discharging end 7 of the magazine, to be transferred into the active shuttle, in the usual way. rlhe said holding and releasing mechanism for each compartment consists in this instance of two sliding bars or blades 9 and 10, whichI are guided at each end, and have projections 9 and 10, see Fig. 2, for the heads and also for the tips of the bobbins, not shown, and which, through the sliding movement of the blades 9 and 10, move from underneath the bobbins to release and drop the same, all as fully shown and described in my pending application, Serial No. 588,017.

Arranged on thel innerside of the plate 7 of 4the magazine, are six vertically moving bars'11, which are loosely supported in guides 7', and have an up and down movement therein. The bars 11 are provided at their upper ends with weighted hooks 12, which are adapted, on their downward movement, lto engage and rock a lever 13, which has its hub 13 secured onarock shaft 14., Through intermediate connections, not

/ shown, from said shaft 14 to a dagger on a transferrer arm, not shown, said dagger is raised into the path of the bunter on the lay, not shown, to trans-ferthe bobbins into the active shuttle, all in the usual and well .known way, andas fully described in Patent No. 933,492, above referred to. l

A bearing 7l on the magazine has loosely mounted therein a llongitudinally moving rod 15; sliding motion is communicated to the rod 15, through angle lever 16, which, through the connector 1-7 from the shifting shuttle boxes on the` opposite side, of the loom, nQt shown, receives a reciprocating movement, to causethe rod 15 to move longitudinall'y into six diderent positions, according to the position of the shifting shut-- tle boxes.

' The longitudinally moving rod 15 has secured thereon, to move therewith, the hub 18 of the operating fingers 18 to which is communicated a rocking motion, through lever 19 and intermediate connections to the replenishing mechanism below, not shown. A rocking movement of the linger 18 will, through its engagement with the extensions 11 on the `vertically moving bar 11, move up or down a selected bar, as shown at the right in Figs. 1 and 3. The bars 11 have at their lower ends. yoke-,shaped heads 11; which, through the pin 11a, which travels in curved or cam-shaped slots '9 and 10 in the sliding blades 9 and 10, communicate a sliding motion to said blades in opposite directions, -to release and drop a bobbin 8 from, its compartment. 7

'All of the above mentioned parts may be of the usual and well known construction,

and as particularly ysliown and described in the axis or fulcrum of the arm 20.

' of the head of the bobbin, to hold the head said Letters Patent, No. 933,492, and in pending application Serlal No. 588,017, above referred to.

l will now describe my improvements in The block 21 carries a stud 23, which has.

pivotally connected thereto one end of a horizontally extending rod or connector 24; the other end of said rod or connector 24 yhas adjustably secured thereon the rod head 25, which is pivotally connected to a stud 25 fast on a downwardly extending arm 27. The arm 27 has its hub 27 Figs. 2 and 4, loosely mounted on a stud 28, which is se-` cured to the inner frame 7 of the stationary magazine. The outer end of the stud 28 has loosely mounted thereon the hub 29 of an arm 29, which extends toward the rear of the magazine, and has its end coincide with A stud 30 on the end of the arm 29 has pivotally connected thereto the upper end of a link or connector 31; the lower end of the connector 31 is pivotally connected to the stud 23 on I the sliding block 21. A bolt or screw 32 on 95 the arm 29 has loosely pivoted thereon the lower end of an upwardly extending latch' 33. rlhe upper end of the latch 33 has thereon a pin 34 extending outwardly, and

,adapted to be engaged by the arm 13a on the lever 13, see Figs. 2 and4, when said .arm 13a moves upwardly through the rocktion, as shown in Fig. 1, by a helically coiled contraction spring V36, which has one end connected to a pin 29 on the arm 29, and

`its other end to a stud 7* on the magazine.

.A stud 37 on the arm 29 has pivotallyv connected thereto the upper end of ka vertically extending connector 38; the lower end .of said connector 38 is pivotally connected to a stud 39 on a lever 40, which has its hub y 40 loosely pivoted on a stud 41 on a stand 42.A An arm 43 extends rearwardlyV from the hub 40 and has an' end 43 adapted to f be engaged by a roll 44 carried; onA the lay, see Fig. 1. p

The arm 27 of the conveyer is provided at its lower end with means to hold the released bobbin in position, preparatory to being transferred into the active shuttle. The lower end of the arm-27 has an enlarged portion 27, see Figs. 5 to 7, provided with a projection on O ne'side thereof, which extends below the magazine and into the path j latch 46 for the tip 8 of the bobbin 8. A

helieally coiled torsion spring 47 acts to yieldingly hold up the latch 46 against a suitable'stop on a collar 48. side of the conveyer 27 has a wire 49 extending outwardly from the boss 27 b. Said wire has loosely pivoted thereon the hub 50 of a latch 50 for the-tip of the bobbin, and the hub 51 on the latch 51or the head of the bobbin 8.` The helically" coiled torsion springs 52 and 53 on the wire 49 act to yieldingly hold upwardly the latches 50 and 51 against the stops on the collars 54 and 55.

From the above description in connection with the drawings the operation of my improvements will be readily vunderstood by those skilled in the art, and briefly is as follows z-When the loom is running normally the parts occupy the position shown ,in Fig. 1, and as the lever` 16, and arm 20 connected therewith, are operated by the shifting shuttle boxes, the swinging arm of the conveyer 27 will be movedto a position under a compartment having bobbins corresponding to the bobbinin the shuttle box which is on a level with the race-way of the lay. Upon the practical or substantial exhaustion of filling in the active shuttle, the replenishing mechanism causes the selected bar 11 to move upwardly, as shown at ythe right in Fig. 1,I

which upward movement acts to operate the blades 9 and l0 to release the lowest bobbin from its compartment, as shown `in Fig. 2. When the bar 1l moves downwardly again, the blades 9 and 10 are again moved longitudinally in opposite directions, -and the lowest bobbin, which has had its preliminary movement, will drop into the conveyer 27. The continued movement of the sliding-bar 11 will, through ythe engagement of the weighted hook `12 on the lever 13,'rock said lever 13 and move upwardly the arm 13, which by its `engagement with the pin 34 on the latchx33, will move upwardly-said latch, and also the` arm 29, see Fig. 3, and through intermediate connections to the sliding block 21, move upwardly said block,

on the-lever 20, and cause, through connector 27, which contains a bobbin, to swing or move to the discharging end ofthe magazine, preparatory to the bobbin being transferred into the active shuttle, in the usual `way. On the 'backwardmovement of the lay, the roll 44 will engage the arm 43, and cause the lever 40 to move downwardly, and

'through intermediate connections to the arm 29, move downwardly said arm 29 and said' block 2l to their `normal-position shown in Fig. 1
